Subject: [PATCH 0/2] sched: Spare IPI on single task renice
Date: Tue, 3 Dec 2019 17:01:04 +0100 [thread overview]
Message-ID: <20191203160106.18806-1-frederic@kernel.org> (raw)
A couple of patches to avoid disturbing nohz_full CPUs when a single
fair task get its priority changed. I should probably check other sched
policies as well...
Frederic Weisbecker (2):
sched: Spare resched IPI when prio changes on a single fair task
sched: Use fair:prio_changed() instead of ad-hoc implementation
